need a new muffler

So my jeep sounds like a bumble bee buzzing. I finally got off my lazy rear to check it out. Muffler rusted in half. I've found several mufflers for a good prices. My question is since its so close to the cat if I cut the cat and muffler apart where do I get a coupler to hook the new muffler back up?

You can get an adapter at any parts store. Then clamp both sides of it. I would recommend a band clamp though. The U-shaped ones at the parts store just oval out the pipe and cause it to leak.

Or get it welded.

Welding is best. U can calmp temporariliy, but it needs to be welded if you wheel it you will rip it off. I clamped my new glasspack on at home then had it welded and a tailpipe bent later at a shop for only $60. A buddy of mine tore his clamped one off three times in just over a year. He had one trip of 80 miles home running nothing but tha cat. Rather unpleasant.

Also if you wheel it, use that as an oportunity to move any piping out of harms way if you can. I ran my tailpipe straight along side the tank skid adn ended it before the back of the tank so hopefully it can't get smashed or hung up on a rock.

don't do any wheeling. Its the wifes ride. In PA exhaust cannot be welded unless you replace the entire system. How stupid is that. Do I get the clamp bigger than the 2.25 inlet/outlet size? or is that the outside diamater?

Where did you hear that rule? I think someone's been telling you bs. Last time I took my jeep to Kost for an inspection, they wanted me to remove the clamps (I did a quick patch job) and weld it up. After I welded it, they passed it no problem.

Thats what they are teaching in their inspection classes. I personally don't know anyone that would fail because exhaust is welded instead of clamped. I must admit its the stupidest thing i've ever heard.

Now, you know, that's just not true.

lol got the new muffler on I welded it and it looks pretty sexy. gotta get the tailpipe on. on the back side of the muffler i have a pipe that will slide in but the tail pipe is too small for the adapter. I had to cut part of the tail pipe out because it was rotted out. I welded the adapter to the tailpipe now its too long. Will work on cutting it down tomorrow. Anybody got a pic of stock tailpipe routing for a 4.0?
